>          Components: JDBC
>    Affects Versions: 10.3.2.1
>         Environment: Sun JRE 1.5.0_08

> When a database residing in a JAR file is open via Derby embedded JDBC connection, the
getSchemas() call on the connection's DatabaseMetaData fails with an exception: ERROR 40XD1:
Container was opened in read-only mode.
> STEPS TO REPRODUCE:
> (1) Download the attached JAR database, BirtSample.jar, and place it in C:\ (or if another
location, update the dbFile variable in  test code below).
> (2) Run the following Java test code, with derby.jar (version 10.3.1.1) in classpath.
> // *** BEGIN TEST CODE
> import java.sql.Connection;
> import java.sql.DatabaseMetaData;
> import java.sql.DriverManager;
> import java.sql.ResultSet;
> public class TestGetDBMetaData
> {
> 	public static void main(String[] args) throws Exception
> 	{
> 		final String dbFile = "c:/BirtSample.jar";
> 		final String driverClass = "org.apache.derby.jdbc.EmbeddedDriver";
> 		final String url= "jdbc:derby:jar:(" + dbFile + ")BirtSample";
> 		final String user = "ClassicModels";
> 		final String pwd = "";
> 	
> 		Class.forName( driverClass );
> 		Connection conn = DriverManager.getConnection( url, user, pwd);
> 		DatabaseMetaData dbmd = conn.getMetaData();
> 		ResultSet rs = dbmd.getSchemas();
> 		rs.close();
> 		conn.close();
> 	}
> }
> // ***END TEST CODE
> The following exception happens in the getSchemas() call:
> Exception in thread "main" java.sql.SQLException: Container was opened in read-only mode.
